IMPROVEMENT `IN MARINE GAMELS.

Specificationforming part of Letters Patent No. 36,745, dated October 2l, iSd-2.

To all whaha it 71mg/ concern/.f

Be it known that I, SAMUEL WooLs'roN, of Vineentown, in the'county of Burlington and State of New Jersey, have invented a new and useful Improvement in Marine Camels; and I do hereby declare that the following is a full and exactdcscriptionthereo referencebein'g had to the accompanying drawings, andto the letters of reference marked thereon. A

In the accompanying drawings, Figure l represents a top view of vmy improvement in marine camels and the mode of applying the s ame to vessels. Fig. 2 represents a-side view of t-he same.

The main portion 'of the camel A may be made Vin the simplest form with a dat bottom. It should be very large. and well constructed; Upon one side of this camel is a series of arms,

B, or platform, upon which the vessel is to rest when fastened to thecamel. The body ofthe camclisdivided into three longitudinal compartments by two partitions, E, Fig. 1; and vt-hc two outer of the compartments are'again subdivided by transverse partitions G. The central is not'thns subdivided. The compart. 'mentson'thc opposite sides of the camel communicate with each other by tubes or waterpassages C, 'provided with stop-coeks I. The operation isas follows: The outer compartments on that side of the -camel next to the arms or platform B are filled with vwater -by pumping or other suitable means, while the other compartments are left empty. This 'cal-eens the camel, sinking the arms B-deep in the water. New, these arms B are brought under the vessel, and the latter is attached to the camel by chains or other suitable means.A rI-hen the stop-cocks I are opened in order to let thewatcr llow through tubes C,Fig.1, into the compartmcuats on the opposite side ot' the.

camel. IVhen the water has reached an equal heighton both sides ol' the camel, or in both of the outer compartments, the stopcocks I are closed, and then the water may be pumped from the compartmentsv next the vessel into thoseon the opposite side of the camel, thus' leaving the middle compartment, and also the roues next the vessel, empty. These empty compartments buoy up the vessel, while the compartment filled with water counteracts the weight of the vessel, thus tending to right the` cameland make it actlikea-lever, 'prying up* the vessel. The force exerted upon the vessel l is in proportion' to the amount of water pumped into the opposite `side of the camel, and can only be limited by the size of the. camel and the quantity of Water employed.

Y As the camel is very simple in its construction, it may be cheaply made kof enormous size,

if desired. l

With this camel a vessel may be buoyed up and carried over a bar in a river with ccm- 'paratively little labor. y The number of compartments and thcgeneral form of the camel may be varied wit-hout departingi'rom my invention.

In raising sunken or grounded vessels two camels maybe employed with appropriate` tackle, the sides' of thetwo camels being -reversed.

Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent of the United States, is#- The above-described improvement in eamels, the same being provided with separate water-compartments on the opposite sides, and arms, or a platform, B. constructed, array ged, and operated substantially.as set tort-h', for the 'purposes specified. .Y v
